In a medium bowl, mash the chickpeas with a fork until mostly smooth but slightly chunky.
Add the ground turkey, parsley, cilantro, cumin, garlic powder, onion powder, salt, and pepper to the bowl and mix until well combined.
Form the mixture into 4 small, thick patties.
Heat the olive oil in a non-stick skillet over medium heat.
Cook the patties for 5-6 minutes per side until golden brown and cooked through to an internal temperature of 165 degrees Fahrenheit.
While the falafel cooks, whisk together the tahini, Greek yogurt, and lemon juice in a small bowl until smooth.
Place the fresh spinach on a plate, top with the warm falafel patties, and drizzle with the lemon-tahini sauce.
